Specification of Letters Patent.

Patented Jan. as, 1906.

Application filed February- 24, 1903. Serial No. 144,627.

To all whom it may con'oerm Be it known that I, HENRY C. SMITH, a citizen of the United States, residing atBoston, in the county of Suflolk and State of Massachusetts, have invented a new and-useful- Improvement in indow Frames, of which the following is a full, clear, and exact description, referen'ce -beinghad to the accompanying drawings, forming a partof this specification in explaining its nature.

My invention relates to an improvement.

I have avoided any objection of this kind by I providingthecast-metal jamb, rough as it may comefrom the mold, with a face or auxiliary' plate 01'' plates, which are secured to .said jamb-casting and which by compensating for any irregularity or roughness in its formation provide true and smooth guidingrunways for the sashes.

, My invention further consists in the adjustment of this face or auxiliary plate or better complates-that they may be trued to position or pensate for the irregularity of rou hness ofform which may jam -casting and be adjusted to hold the sash or sashes withbetter security and guide them more accurately.

My invention further consists in other novel features of adaptability incident to the arts just referred to, but which features can better be seenandappreciat'ed by a detailed description in connection with the drawings,

where1n} j Figure 1 shows the window embodylng my improved frame construction in longitudinal 2 shows thewindowvertical section. Fig. p in horizontal cross-section and with certain details of construction to which reference will be hereinafter made. Figs. 3 an'dfishow the window in vertical section with special details of construction to .which reference will hereinafter be made. Figs. 5 i and ,6

-show my improved frame structure as apexist in the plied to a pivoted sash. Figs. 7 and 8 show my improved frame structure as applied toa fixed sash.

Referring to the drawings, :A represents the head of the frame, B the sill, and C re resents theside portions of the frame or t e jambs. The head, sill, and jainbs are made ether. The'head and sill castings have a formation by which they will be. best suited to the kind of sash or sashes which they inclose and are also formed with reference through holes 0', formed in the casting of the while nuts 0 receivin the ends of said bolts, com lets the union 0 the cast parts. This 'met odof union is a desirable one in the fact 'thata certain amountof play is given to the parts for obtaining more or less of an adjustment in order that the partsmay be fitted together as evenly as possible. The special advantage of the. method of union'consists in the fact that the parts can be united without any special preparation or, in other words, just as they come from the mold, no boring or other finishing being necessary.

The castings forming the chambers are substantially alike on both sides of the win-- dow, except when they may help form the boxes for the window-weights, if such be used, or made so that they may be joined to one 'anotherto form a continuous structure, as when .there is a row of windows, as will hereinafter be explained;

The structure. ofthe jamb-castings is best seen in-Figs; 1 and 2. Each casting is provided. with the inside and outside molded edges 2: '0, which form the side Walls of the window-on the inside and outside adjacent to thejambsan'd extending, of course. its vertica flanges extend the entire vertical length of up of separate pieces of cast metal bolted toto their architectural, fitness; but to this ref-' union of the castings is secured, are passed jamb pieces, and slipped into slots at b, formed in the said-lugs a, and b, respectively,

length. Projecting inward from the main casting are the two flanges c 0. ,Theseconfine myself to this special form of jamb'-' casting; but it is a practical one as embodying the principles of my invention;

Now, as before stated, the objection to using the cast-metal frame, and especially the j amb portions'of the frame, is that the casings could not be made true enough simply by their molding to serve as guides for the sashes, but runways would have tc be laned out, and this, together with other finishing, is so expensivethat it in the past has practlcally precluded the use of the cast-metal frame or jamb; Accordingly I do not endeavor tojprovide runways for the. sashes with my cast-metal j amb, but take the cast ing just as it is, rough from they mold, and provide it with a face or auxiliary plate of sheet metal, which actsto hold and guide the sashes. This face-plate in the drawings is designated D, and it has the substantial con-' figuration shown in Fig. 2, or any .otherconfiguration, for that matter, which best suits it for'the sash or sashes which it serves to hold or guide. I jamb-casting by itsoutside and inside edges (Z d being turned to fit around the flanges c 0, extending inwardly from thejamb-casting, as before explained, and which edges are then bolted to the said flanges by the bolts (2*. the rib extending from the jamb-casting, as before referred to. The sheet-metal face is thus rigidly held in place secured to the jamb-casting, and it serves to provide smooth and accurate guiding-runways for the sash.

or sashes. Of course, as sai before, by the use of the sheet-metal face-plate as a supplementary member I am able to procure such a sash retention and guidance as might be optained by the cast-metal jamb alone, but only at great expense, which difficulty itis' the purpose of this feature of my invention to overcome. The face-plate is, as it were, a finishing-facing applied to thejamb-casting. It covers the jamb-casting and conceals an unsightly roughness and compensates for a l irregularities in its formatlon.

.words, I am able to use a jamb-casting rough, just as it comes from the mold, Without any finishing whatever. All planing and other finishing is entirely eliminated. Moreover, the face-plate is adapted to beused'for the retention of any sash. Its especial applicability is for the retention and guidance of the sliding sash; but it can be used for the rtention of a pivoted sash as well.

The'face-plate is secured to the The plate is reinforced at the center by In other v placed rectangularslots 0. These slots have Another feature of importance as further ing the advantageous use of the face-plate consists in the fact that it is made adjustable relatively to the j amb-oasting. I t will be noted that when the face-plate is secured to the. 'amb-casting the screws or bolts (Z which.

hol the face-plate to the flanges c c on the jamb-casting, pass through slots c, which extend in horizontally from the edges of said flanges to which the face-plate is fastened. These slots permit of a certain amount of lateral play to the bolts or screws securing the face-plate, whereby the face-plate becomes adjustable not only to better compensate for any irregularity which may exist in the jarnb-casting, but also permitting the faceplate to be trued or evened to better hold-and guide the sashes. The slotted means thus shown for obtaining the adjustment of the face-plate is desirable in the fact that it can be obtained in the original jamb casting without finishing of any kind or the addition of any supplementary part.

The faceplate is made of any suitable material, such as sheet metal, copper, or sheetsteel covered with copper or any other noncorrosive material. ing-surfacing along the runways is a desirable adjunct in the formation ofthe face-plate.

' The cast-metal jamb, with its sheet-metal face-plate, is especially adapted to be used with a window or other sash having overbalancing-weights. The casting can easily be formed to provide proper weight boxes or casings. Then the-castlng maybe made with A non-corrosive wear-' IOC openings, as openings c ",which allow the entry of the weights. through them into their boxes or casings. Any opening of this kind would of course be covered by the face-plate, and in this connection I might say that I preferably make the j amb-casting in a skeleton form as tending to secure economy in material. Assaid before, any opening thus left would be covered by the face-plate.

The special aptitude of the jamb-casting for usewith a sash having weights is also seen in the means provided for the retention of the pulleys over which the cords .or chains run which connect the sashes with their overbalancing-weights. This may'best be seen. in Figs. 1,2, and 3.

The pulley, which is designated E, is inclosed in a casing e, which has an opening 'e in its under side through'whichthe sash-cord extends, as is common with such casings. The pulley is held in place by its casing being secured to the jamb-casting in the following manner? There is molded in the jamb-casting at the point Wherethe pulleys are to be eveled side edges 0 (See Fig. 2.) The pulley-casings e are made to fit into these slots, the forward edges of the casings at e being beveled to rest a ainst the beveled edges 0" of the said slots ormed in the jambcasting, while the casing rests along its lower front edge e on the lower edge 0 of the slots as a source of basal support. With this method of securing the pulleys, or rather their cases, no further fastening is required, for the load of the weight through the medium of the sash would hold the pulley in place fixed in its slot. In order, however, to prevent the dropping out of the pulleys in case they were inserted before the janib-casting was set in place in the wall, there are shown bolts e, which pass through the jamb-casting at about the points 0 and fasten through lugs e projecting from the under side of said pulley-casings, slots being cut in said lugs to permit of the entry of the bolts. The ends are secured in the ordinary manner by nuts. The holes where the bolts e pass through the ja'mb-casting in order to secure the pulley-casings are preformed in the original casting, and in'this connection it is to be especially noted that one feature of my invention as regards the jamb-castings, andfor that matter the head and sill castings as well, is that they are so de signed that absolutely no machine-work of any des'cri tion is required to fit or adapt them for t eir combination or the reception of any supplementarypart, not even the drilling of a single hole. a

Reference has already been made to the fact that the jamb castings are alike in their construction and in general, and especially with respect to an individual or isolated window the castings are formed substantially as before described; but where there is a row of windows the castings can be made so as to traverse the spacing between any two windows and rovidea jamb-support at either side of each. This construction of the casting may be seen in Fig. 2, where the whole casting is designated C C. This form of-casting is desirable as tending to great strength and ri idity of frame structure, especiall since t e casting is bolted to the head and si 1 of separate windows throu h the medium of the lugs a and b, as before escribed, and the head-castings and the sills of the separate windows are also bolted together, whereby there is formed acontinuous structure. The head-castings and also the sill-castings-are bolted together by being made so as to extend to abut or come together approximately at a central point between the windows in which they are contained, and then by means of lugs projecting from them and placed contiguously theseparate castings are bolted toether, the bolts passing through the lu s.

or example, in Fig. 21 have shown two 51 lcastings bolted together. The ends of the castin s meet or abutat a point centrally located between the windows, and they are shown as having the lugs b projecting from them, and through these lugs the bolts b ex:

tend, the ends ofwhich are properlysecured.

by nuts. The head-castings, are bolted together in the same way. There is thus obtained a framework of great rigidit and strength, which is especially to be desired in modern building an which also admits of any architectural matter being built upon or secured to it as a source ofsupport. The

modified form of jamb-casting just referred seen at Fig. 2 at the left, (where if wei htboxes are necessary) they can be forme as supplementary parts by means of the sheetmetal box-forming plate G, and the aptitude is to be observed with which the plate G can unite with its corresponding jamb-casting by bending the edges 9 g of the plate around the flanges c c", which run along the inside of the jamb-casting, as before ex lained, and then fastenin the said ed es 0 the plate to the flanges y the same olts or screws which secure the face-plate D, that is also fastened to these flanges. As for the head and sill castin s A and B, respectively, they are forme or may be formed so as to be best adapted forthe purposes of support and retention which the serve to obtain and also with regard to t eir architectural fitness.- The cast head can be extended and formed with stiffening-ribs A in such a manner as to support the wall overhead, thus saving the lintels that are usually used for this purpose, while the cast sill can be extended to cover the wall in such a manner as to take the place of a stone sill. (See Fig. 4.)

Reference has alread been made to the fact that the castmeta frame or jamb ortions thereof, with its face or auxiliary p ate of sheet metal, is as well adapted to be applied to a pivoting-sash as it is to a sash that slides, the diiference only being one of configuration, which is immaterial in so far as the essence of my invention is concerned. In Figs. 5 and 6 I have shown as an example of such the aptitude with which a face or auxiliary plate such as I have described made of sheet metal may be ap lied toa pivotinge sash. The face or aux1 iary plate is designated-D and the sash D the sash bei'ng pivoted tothe plate by any suitable form of plvotal connection (1 The plate, it is to be noted, is

- adjustably secured to the flanges 0 def the be seen in Fig. 5, they are formed by bending or forming the plate along its outer edge, so as to form a groove d, which receives a complemental member (1 extending from the corner of the'sash, while below the said pivotal points of turning they are formed by bending or forming the metal at the corner of the sash to form a groove (1", which receives a combe made of two auxiliar to the flanges c c of the and adjustably, if need *be, as heretofore ex plained. These finished plates serve to cover. any unsightly roughness in the casting of said frame or compensate for any irregularity;

plemental member (i formed by a fold in the plate D, and thereby securing in both cases when the sash is closed a weatherproof jointure. i y In Figs. 7 and 8 I have shown the aptitude with which the cast-metal frame, with its face or auxiliary plate or plates, can be used for.-

the retention of a fixed sash or one which is permanently secured .to the frame. The side rail of the sash securing the glass pane may plates 1), secured ame by the bolts d therein. The flanges c c also provide-every good means for the retention of this kind ofl frame structure. i

There is shown in Figs. 7 and 8 in the cast-'1- ing 0 an additional feature of construction to any that has heretofore been referred to and .which comprises flanges or what may be one is shown.

termed an anchor-hook a, by which the same casting is anchored, as it were, to the masonry. In Fig. 7 the casting is formed with two of these back supports, While in Fig. 8 but This feature is one which might be employed to advantage with the jamb-casting of any kind of window,'forit would prevent any possibility-of the'casting warping out of the wall in case of fire.

Reference has been made in thespecification and appended claims to the face or auxiliary plate or plates over the jambs as of sheet metal. By 'sheet'metal is meant any smooth-finished metal plate or platesof the pro or configuration, whether such be'formed by ending the plate or plates into shape or rolling it.

Although the laterally adjustable sheetmetal face or auxiliary plate hereinbefore d6? scribed is especially designed for cast-metal framework, yet it might be successfully applied to thejarnb portions of any frame struc-' ture, especially if such be roughly finished, the face-plate of course compensating for any irregularity or roughness in the structure and --may providin the sash Having thus fully described my invention, 1 claim and'desire to secure by Letters Patent of theUnited States 1.
